GRADING-MACHINE.

Specification of Letters Patent.

Application filed October 23, 1911.

Patented May 14, 1912.

Serial No. 656,122.

To all whom it may concern Be it known that I, ROLAII A. BAKER, acitizen of the United States, residing at Rice, in the parish ofCalcasien and State of Louisiana, have invented a new and usefulGrading-Machine; and I do hereby declare the following to be a'full,clear, and exact description of the invention, such as will enableothers skilledin the art to which it appertains to make and use thesame.

This invention relates to a new and useful combined levee and roadgrader attachment, adapted for use in connection with plows forconstructing levees in rice fields or the like, whereby the field may beproperly irrigated.

The old or general method for constructing levees is to use what isknown as a disk plow to start the levees, and, subsequently, utilizewhat is termed a pusher for grading them. In this old or general method,from eight or more head of mules are used to pull the disk plow, and thesame to pull a pusher or grader.

The present invention aims to provide a novel combined means forconstructing and grading the levees at the same time, which means may bedrawn by seven or eight head of mules, or possibly less, which will savetime, as well as labor, in going over the field twice.

One of the objects of the invention is to provide a grading wing adaptedto be connected to the moldboard of the plow, and so adjusted as tograde or top off the levees. The connection between the grading wing isto be such, as to permit the wing to be adjusted vertically orhorizontally.

A further object of the invent-ion is to provide an extension on theland side of the plow, with means connecting between it and the gradingwing for holding the grading wing adjustable horizontally with regard tothe extension.

A feature of the invention is the provision of an extension wing hingedto the end of the grading wing.

A further feature of the invention is means connecting between theextension wing and the free end of the extension of the land side of theplow, for holding the extension wing adjusted at various angles withrelation to the grading wing.

A further feature of the invention is the provision of a gage wheelcarried by the beam of the apparatus and having means whereby the samemay be adjusted, to regulate the depth of the plow, to uniformlyconstruct the levees.

The drawings only disclose one form of the invention, but in practicalfields this form may necessitate alterations, to which the patentee isentitled, provided the alterations are comprehended within the scope ofwhat is claimed.

The invention comprises further features and combinations of parts, ashereinafter set forth, shown in the drawings, and claimed.

In the drawings, Figure 1 is a view in side elevation showing thegrading machine constructed in accordance with the invention. Fig. 2 isa plan view. Fig. 3 is a transverse sectional view on line 38 of Fig. 2.Fig. 4 is a detail view of one of the connections between the meansconnecting the extension of the land side of the apparatus and thegrading wing. Fig. 5 is a detail view of the connection between themoldboard and the grading wing.

Referring to the drawings, 1 designates the usual form of plow, having amoldboard 2 and a land side portion 3. The plow 1 is provided with theusual beam 4;, to which is clamped a cutter blade as shown at 6. Thelower end of the cutter blade is secured to the forward end of the plow,as shown at 7. Secured by clamps 8 to the beam is a plate 9, which isprovided with a downwardly extending extension 10, the lower portion ofwhich is provided with a racked quadrant 11. Pivoted to the extension,as at 12, is a lever 13. Journaled in bearings of the lower end of thelever is the stub shaft 14 of the wheel 15. The upper end of the leveris provided with a dog 16, designed to engage the teeth of the quadrant,for holding the lever and the gage wheel in adjusted position. The upperend of the lever is provided with a hand grip 17 having a rod connectionwith the dog, as shown at 18, whereby the dog may be actuated to releasethe lever, so that the same and the gage wheel may be adjusted.

The forward end of the beam 4 is provided with the usual connections 19whereby an evener or equalizer may be connected, for drawing theapparatus through the field.

The plow is provided with the usual handles 20 having braces 21 betweenthem and the beam.

Bolted, or otherwise connected, as shown at 22, is an extension 23 tothe land side of the plow. This extension 23 may or may not be providedwith disks 24. The disks 24, however, are only utilized when grading aroad. In grading a road, the disks bury into the road, for holding theapparatus straight to its work, so that the grading wing 25 will throwthe dirt entirely to one side of the apparatus. The grading wing 25 ishinged as at 25 to the part 25 which is provided with an aperture 25 toreceive the hook 27 of the moldboard 26 of the plow. By thisconstruction the grading wing may be adjusted, vertically andhorizontally. Hinged to the free end of the grading wing is an extensionwing 28, which may be thrown at various angles, when grading or toppingoff the levees. It is to be understood that by connecting the gradingwing to the moldboard in the manner shown, the grading wing will be soarranged as to strike the upper portions of the levees, whereby they maybe properly graded or topped off. A brace member 29 connects between themoldboard and the land side of the plow.

A plurality of telescoping rods 30 are provided. These rods, at thepoints where they telescope, are provided with a plurality of apertures31 which receive the pins 32, that is, when the apertures are inregistration, for holding the rods in adjusted position. One end of eachof the telescoping rods has universal connections 33 with the gradingwing and the extension 23, so as to permit the telescoping rods to bemoved as the grading wing is adjusted. The universal connections 33comprise the pins 33 at the end of the telescoping rods 30, which pinspenetrate the sleeve 33 having lugs 33, which are ournaled in brackets33. Nuts 33 are threaded to the upper ends of the pins 33, as shownclearly in Fig. 4.

Connecting between the grading wing and the extension 23 by universalconnections 34: are rods 35. The rods 35 consist of two parts, theadjacent ends of which are provided with right and left threads 33,

with which the turnbuckles 37 eoiiperate, so as to hold the grading wingproperly in position with relation to the extension 23. By adjusting theturnbuckles, the grading wing may be adjusted toward or from theextension 23.

A pair of telescoping rods 39, similar to the rods 30 and havingapertures and pins 40 and 41 for holding them in adjusted position, areconnected between the extension wing and the free end of the extension23. The rods 39 have flexible connections 42 with the extension wing andthe wing 23.

From the foregoing, it will be noted that a new and useful, simple andeffective grading machine has been devised, for grading or topping oflevees or grading a roadbed, and one which has been found to bepracticable.

The invention having been set forth, what is claimed as new and usefulis:

In combination with a plow, a grading wing adjustably connected to themoldboard of the plow, an extension connected to the land side of theplow, telescopical rod connections between the extension and the gradingwing, rods having turnbuckle connections between the wing and theextension whereby the wing may be brought toward or from the extension,means carried by the telescoping rod for holding the wing when adjusted,an extension wing hinged to the grading wing, means for holding theextension wing adjusted at various angles relative to the grading wing,the telescoping rods having universal connections with the grading wingand the first extension. means for holding the grading wing in adjustedposition vertically, and an adjustable gage wheel and cutter for theplow.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
